SPECIFICATION forming partof nettetgi atent No. 654,7 dated J V 31,1900- Application filed r1115 8, 1899. ,Seriallio. 723,233. (No model.)

To all whomit-may concern;

Be it known that I, MARION NOEL SCHAUF- FLEBERGER, a citizen of theUnited States,re-

siding at Bristol, in the county of Washington and State of Virginia,have invented new anduseful Improvementsin Pneumatic Water-Elevators, ofwhich the following is a specification. I

My invention relates to pneumatic waterelevators of that class orcharacter in which a tank is located in a well, mine-shaft, or otherplace and isprovided with an inletvalve, an outlet-pipe, and an air-pipefor forcing air into the tank, whereby the water is displaced from thetank and forced up through the outlet-pipe to the top of the well orshaft.

The object of the invention is to provide an improved construction ofWater-elevatorwhereby when the water in the tank falls below apredetermined level the air-pressure will be automatically reduced bythe open-.

ing of a valve in ,an exhaust-pipe, allowing water to enter the tankuntil the proper level is reached,- whenthe valve will close and thewater be forced up the outlet-pipe.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a central longitudinal sectionof a water-elevator constructed in accordance with my invention. Fig. 2is a detailed sectional View of a modified construction of the air-pipevalve.

In Fig. 1 I haveshowna double-acting elevator provided with a housing 16at the upper end, with which the air-pipe 5 communicates. The tank isdivided bya central partition 17 into two compartments 18, in each ofwhich are located an outlet-pipe 3, exhaustpipe 7,- pivoted arm 8, valve9, float l3, and inlet-valve 2.- The outlet-pipes come together abovethe tank and are connected with a single discharge-pipe. (Not shown.)Located in said housing is a horizontal lever 19, each end of which isprovided with a valve 20, which engages with a seat 21 in the upper endof short air-pipes extending into the tank. Said lever is alsoprovided'with rods 23, which pass down through the said air-pipes andare provided with arms 24, the lower ends of which are formed withslots, through whichthe arms 8 loosely pass. The operation of thisconstruction will be readily understood. As one *fiqat rises to closethe exhaust-P pers that theairQpressure will force the water 'out of theoutlet-pipe, the float in the other compart ment will fall to reduce theair-pressure and allow water to enter the compartment. By this means theoperation of elevating the water will be continuous, as while onecompartment is discharging the other will be filling. A suitablestrainer may be placed at the lower end of the tank, as is usual inwaterelevators.

In Fig. 2 I have shown a modified construc-' tion of float and valve forthe e haust=pipe. In this instance the numeral 25 designates averticallymovable tube telescoping upon theeXhaust-pipe'and provided at the upperend with an arm 26 and at the lower end with a float 27. Said tube isformed with an open ing 28, adapted to register with a correspondingopening 29 in the exhaust-pipe. The 0poration will be readilyunderstood. When the float falls, the said openings will come intocoincidence and the air in the tank will escape through theexhaust-pipe. When the float again rises, the openings will close. Thenumeral 29 designates a rubber bumper carried by the float.

Having thus fully described my invention, what I claim is% In a dnplexpneumatic water-elevator, the combination with the tank divided byacentral partition into two compartments, each having an inlet-opening inthebottom provided with avalve, the outlet-pipes, the exhaust-pipes, thepivoted arms provided with valves,the rods pivoted thereto and thefloats, of the housing at the upper part of the tank,

the air-pipe communicating therewith, the I pivoted lever having a valveat each end, the air-pipe with which said valves engage, the rodsconnected with said lever passing through said air-pipes, and the barsconnected therewith having slots at the lower ends through which saidpivoted arms pass, sub- .stantially as described.

In testimony whereofl have hereunto set myhand in presence of twosubscribing witnesses.

MARION NOEL SOHAUFFLEBERGER.
